Senate leaders emerged Tuesday from a closed-door meeting with the National Security Agency chief saying the story about the American who leaked details about secret U.S. surveillance programs is enveloped in misinformation and called for public hearings.

“It’s not possible for Congress to do the kind of vigorous oversight that (President Obama) spoke about if you can't get straight answers," Oregon Democratic Sen. Ron Wyden said following NSA Director Keith Alexander’s meeting with members of the Senate Select Committee on Intelligence.

"It's appropriate now to have public hearings,” Wyden continued. “This will give the committee and the American people the opportunity to look at the disclosures that have come out here in the last 10 days or so. And I think that's the appropriate next step."
